Hi Reinoud,
I have a color-filled contour plan view in IDV. I defined a color
scale for it with a limited number of colors (using the Radar DbZ
scale as a start and extending it from 16 to 20 colors) and saved it
as a bundle.
When I am now using ISL to generate images, the contours are correctly
using my color scale but the color bar is drawn using too many colors
(it looks like the maximum of 16 million). I would like it to be drawn
using the same number of colors.
This is my colorbar tag:
<colorbar
display="class:ucar.unidata.idv.control.ContourPlanViewControl"
orientation="right" interval="0.2"
width="20" height="300" showlines="true" anchor="UR"
place="UR,-70,10" showunit="true"/>
This past summer we did away with the non discrete color bar preview
icons that we use in places like the legend and the menus. But, this
didn't get implemented in the ISL colorbar. It now is and will be in
tonight's nightly build.
Another point: is it possible to have the colorbar values increase
upwards instead of downwards?
We don't have a way of specifying that in the ISL but what you can do
is in the IDV edit the color table used by the display. Right click in
the color bar and there should be an "Invert table" menu item. This just
flips the color bar. Now, in the display change the range to the
opposite range, e.g.. if it was 0-45 change it to 45-0.
